SCOT-COLLECTING APPARATUS.

Application filed May 29, 1928, Serial No. 281,562, and in Cuba March23, 1928.

This invention relates to the collection of the soot carried along bythe smoke issuing from the chimneys, whatever its class, and its objectis to provide an apparatus of new and improved construction forabsorbing the soot carried by the smoke that goes to discharge in theatmosphere, avoiding the falling down of same and thus filling therequirements of the sanitary ordinances for chimneys on industrialstores within the suburban limits of towns.

The invention is described with reference to the figures of the encloseddrawings, in which Fig. 1 is a side elevation of the apparatus which isthe subject matter of this invention.

Fig. 2 is an upper plan view of the same.

Fig. 3 is a longitudinal vertical section of the apparatus on the line33 of 2.

4 is a detail, showingin diametral vertical sertion, the upper portionof" the chimney or". the apparatus, showing the cleaning device forscraping the soot in its uppermost position.

And Fig. 5 is a detail in horizontal section, on the line 55 of 4.

This apparatus comprises a box in the form of a rectangularparallelepiped 1, made of iron plate with the angles reinforced byangular plates 2, and having its bottom 3 in the form oi an inclinedplane, with a tilt higher than 37 so that the soot may slide easily oversame towards its lowermost end, where there is installed a funnel orchannel 4 discharging into a drawer or box 5 which preferably isremovable by means of sliding guides 6. Instead of this drawer or box 5,a descending tube may be used for carrying the soot thus deposited to apoint below the floor where the apparatus is located. The box 1 issupported, on its lowermost end, by means of two short metallic uprights7 and on its uppermost end by means of a metallic supporting frame 8that is tied to the bottom of the box by means oi two iron plate braces9.

The inner space of the box 1 is divided into two compartments by meansof a division plate 10, which descends from the upper portion to acertain distance from the inclined plane 3 formed by the bottom, inorder to form a restricted passage for the smoke arriving at the box,the inlet of such smoke being effected by means of a curved tube made ofiron plate 11, discharging into an opening 12 made in the upper part ofthe compartment 18, said tube 11 being the end of the chimney 14 thatcarries the smoke from any furnace or hearth where coal is used as afuel. In the upper part of the other compartment 15, which is of lessdepth than compartment 13, is mounted a chimney tube of iron plate 16,passin through an opening formed in said upper part, said chimney tubeextending down a certain distance below said upper part, in order toforce the smoke to come in contact with said upper part before enteringsaid chimney tube 16. The tube 16 has on its upper edge a reinforcingring 17 of angular section, from which projects laterally a bracxet 18on which is rotatably mounted a hinged cover 19 that serves to. coverthe chimney tube 16 when the apparatus is inoperative, said cover. 19having a short arm 20 to which is tied a rod 21, the lower end of whichends in a handle or hold 22 at a convenient height for easy handling.Within the chimney tube 16 and on its upper end are fixedly placed twoparallel cross bars 23 that support rotatorily between them a verticalsheave 2% that serves as a guide for a chain or cable 25 going outthrough a slot or cut 26 made in the wall of said tube 16 and thendownward on the outside, being guided by another sheave 27, rotatablymounted in a supporting piece 28 fixed to the wall of said tube 16, saideablc or chain 25 carrying on its end a globe formed by three metallicrings 29, 29 and 29", in planes perpendicular to each other, twovertical and one horizontal, of which the horizontal one has adhered toit a brush or scraper of wire bristles 30, the outside diameter of whichis approximately equal to the inner diameter of the chimney tube 16 andin the lower part of the vertical rings 29, 29 is suspended acounterweight 31.

One of the side walls of the box 1 has an opening that is closed bymeans of a hinged door 32 that is held in the closed position by meansof closure latches 33 and the object of which is to allow an ocularinspection of the inside of the box as well as the cleaning of same whenthis is necessary.

The outside end of the cable or chain 25 is tied to a hook or staple 34fixed on the outside of the box 1, so that in the stressed position ofthe chain or cable 25, the globe formed by the three rings 29, 29' and29 is held hanging at a height lower than the inunderstood that it canbe installed anywhere and at any convenient height.

The operation of the apparatus is as fol.-

lows: the smokecharged or saturated with soot coming from any furnace orhearth where coal or other fuel is used, enters the compartment 18 ofbox 1, arriving to same via the chimney 14 and through the curved tube11, and within said compartment 13 it is forced to descend through tothe division plate 10 to pass through the passage formed between thelower edge of same and the inclined bottom 8, and upon the smokestriking against said division plate 10 and bottom 3, a part of the sootcarried by same is deposited upon the bottom 3 and then the smoke goesupward through the other compartment 15 of the box 1 and to the upperpart, but due to the downwardly extending lower end of the chimney tube16, the smoke is forced to descend in order to enter this tube, saidretroc ession favoring the precipitation of another portion of the sootcarried by the smoke upon the bottom 3. The smoke going upwards throughthe chimney tube 16 deposits the remainder of the soot therein so that alayer of soot is formed in said tube the thickness of which may varyaccording to circumstances.

The soot deposited upon the inclined bottom 3 passes downward along sameon account of its own weight and falls through the funnel or channel 4into the drawer or box 5, being collected there or being left to fallthrough a downward tube that not shown, to a convenient storage place.

hen the tube 16 needs to be cleaned, the chain 25 manually operated tomove the cleaning globe upwardly and downwardly in said tube, said globescraping the soot from the inner side of the wall of the tube and thesaid soot drops on the bottom 3 and by its own weight or gravity slidesdownwardly thereon and through the opening 1 into the drawer or box 5,where it is collected.

It is obvious that the form of the box and the constructional details ofsame and of the apparatus for cleaning the chimney tube may be varied,without thus altering the es sential character of the invention, whichis as hereinafter claimed.

What I claim is 1. A soot collecting apparatus comprising a closed boxhaving an inclined bottom, a division plate that descends from the upperpart of the box to a certain distance from the bottom and divides thebox into compartments, an inlet tube for the smoke in the upper part ofone of the compartments and a chimney tube in the upper part of theother compartment.

2. A soot collecting apparatus comprising a closed box having aninclined bottom, a division plate that from the upper portion of the boxdescends to a certain distance from the bottom and divides the box intotwo compartments of unequal depth, an inlet tube for the smoke in theupper portion ofthe deeper compartment and a chimney tube in the upperportion of compartment of less depth.

3. A soot collecting apparatus comprising a closed box having aninclined bottom, a division plate that descends from the upper portionof the box to a certain distance from the bottom and divides the boxinto two compartments of unequal depth, an inlet tube for the smoke inthe upper portion of the deeper compartment and a chimney tube in theupper portion of the other compartment of less depth, said chimney tubehaving a lower inlet end extending downwardly to a certain distancewithin the box, in order to cause smoke to be deflected downwardly inorder to enter in the chimney tube.

4. A soot collecting apparatus comprising a closed box having aninclined bottom, a division plate that descends from the upper portionof the box to a certain distance from the bottom and divides the boxinto two compartments, a soot collector located in the lower end of thebottom, an inlet tube for the smoke in the upper portion of the deepercompartment and a chimney tube in the upper portion of the othercompartment of less depth, this chimney tu e havii a at its end an inletportion to a certain distance within the box to cause smoke to bedeflected downwardly in order to enter the chimney tube.

In witness whereof I atlix my signature.
